SPRINGFIELD - A former tanning salon owner, already facing charges for secretely videotaping customers, has been indicted on child porn charges. Federal prosecutors filed a seven-count indictment Wednesday charging 34-year-old Brett Patrick Kent with producing and possessing child pornography. Kent failed to appear at a hearing Tuesday, so the judge issued a warrant for his arrest. Images on a computer at 360 Degree Tan showed female customers dressing and undressing on tape from a hidden camera.The federal indictment said 15,000 images and 53 video files were in Kent's home. Greene County prosecutors charged him a year ago with 22 counts of putting a camera under one tanning bed and taping customers without their permission, and 13 women filed civil lawsuits against Kent for invasion of privacy.
